This invention relates to improvements in door :hinge structures and more particularly,

venient assembly and disassembly; in which adjustments can be simply and quickly made without disassembly of parts; and which is positive in action and not likely to get out of order in service. a

' Further objects of'the invention are in part obvious and in part will appear more in detail hereinafter. a a

The invention will be readily understood tromthe followingdescriptionthereof, taken in connection with the accompanying drawing in which Fig. 1 is alcentral vertical sectional view on the line 1-1, Fig. 2, a part only [of the door post being in elevation; Fig. 2 is a 'view in end elevation of parts of the upper-and .lower hinge connections and in vertical section through the door; Fig. 3 is a perspective view of the cam member of the lower hinge .connection; and Fig. 4 is .a cross sectional view ihrough the door post, on the line. 4-4,

ig. 1. Y I

In the embodiment ofthe invention here illustrated, A represents a suitable door post to which a-door B is hinged, said postandsaid door being of any desired construction. The

post here shown is of sheet metal witha lon gitudinally disposed channel orgroove 1 in reach of the four sides thereof.

'Hinge connections are provided between the top of the door and said post and between the bottom of said door and said post, as is usual, the hinge connection in each case comprising two cooperating hinge parts, .a stationary part secured to the door post and a movable par-t secured to the door.

The movable hinge part of the upper hinge connection includes a one-piecehinge pintle having an upper end portion .5 of generally.

cylindrical form, .a lower end portion 60f non-circular shape in cross section and an intermediate collar 7' of generally annular form. Said lower, non-circular pintle portion iswadapted to fit a correspondingly shaped, vertically disposed opening 8 in the top portion of the door and the pintle collar 7 is adapted to rest uponsaid door top portion. To firmly secure the pintle to the door, a suitable anchoring plate is provided, said plate havinga generally rectangular top porrtion l3 and a pairof correspondingly shaped depending flanges 14 adapted to extend alongside .the door sides and secured to the door by one or more bolts 15 extending through said door and said plate flanges. Said plate .topportion is provided intermediate its ends with an upward offset 16 to provide therebelow a cavity or recess 17 for the pintle collar, said olfset being provided with a circular opening 18 through whichrthe upper cylindricalportion .5 of said pintle extends.

The stationary hinge part of the upper :hinge connection includes a one-piece socket member 20 having .a vertically disposed, gen .erally cylindrical socket 21 adapted to receive the cylindrical upper end portion 5 of the pintle of the movable hinge part. Said socket member is alsoprovided with a gen erally rectangular base portion 22 fitting and secured within a channel 1 of the door post A by one or {more bolts 23 extending through said post and through said base portion.

The stationary hinge part of the lower binge connection includes a bracket having a vertically disposed generally rectangular securing portion and a generally circular supporting portion #31 extending outwardly at right angles from the top of said securing portion, said portions being connected at their sides by' webs 32 (for purposes of strength) S a-id bracket securing portion fits and is secured within a channel or groove 1 of the door post A by one or more bolts 34 extending through said post and through said securing portion. Mounted upon the upper surface of the supporting portion of said bracket is a tubular cam member 35, the an nular upper cam edge of which is inclined downwardly in opposite directions, as at 36 and 37 from a high dwell or stop point 38 to a low dwell or stop point 39 diametrically opposed thereto.

Said cam member is provided at its base or lower end with an outwardly extending annular flange 40 and with an inwardly extending annular flange 41, the latter being engaged by the non-circular head 42 of a hollow bolt having its shank 43 extending downwardly through a centrally disposed aperture 44 in the bracket supporting portion 31. The sides of said bolt head are engaged by the portions 45 of said cam member, which portions form a non-circular recess for said head and effectively prevent turning of said bolt. A nut 46 is threaded on the lower projecting end portion of said bolt shank and by screwing up said nut, said cam member is firmly secured upon said bracket supporting portion, as will be readily understood.

The movable hinge part of the lower hinge connection includes a one piece pintle having a generally cylindrical body portion 51, a reduced upper end extension 52 of non-circular shape in cross section and a reduced lower end extension 53 of generally cylindrical form. Said non-circular top extension 52 is adapted to fit in a correspondingly shaped opening 55 in the door B and said cylindrical bottom extension 53 is adapted to fit or seat in the correspondingly shaped opening 56 in the bolt 43 which secures the cam member 35 on the bracket supporting portion 31. Said pintle body portion, near its lower end, is

provided with a laterally extending tapering boss 60 terminating in a reduced stud 61 on which is rotatably mounted a ball-bearing roller 63 for movement along the cam surfaces 36, 37 of the cam member 35. Said roller is held on said stud by a'screw 65 threaded into the end of said stud and having its head 66 engaging said roller, as clearly indicated in Fig. 1.

Preferably and as shown, the lower hinge connection includes a wear-resisting door plate similar to the anchoring door plate of the upper hinge connection. The door plate of said lower hinge connection includes a generally rectangular wear-resisting body portion 70 extending along the lower edge of the door and two upwardly extending, correspondingly shaped flanges 71 extending along the sides of the door and secured to the door by one or more bolts 72 extending through the door and through said flanges. The plate body portion 7 0 intermediate its ends is, of course, provided with an opening '73 through which extends the non-circular upper pintle extension 52.

To conceal the working parts of the lower hinge connection, with consequent improvement in the appearance thereof, an inverted cup shaped enclosing cover member is provided, said member enclosing said cam member, the pintle body portion 51 and the roller 63 carried thereby. The lower end of the tubular side wall 80 of said enclosing member rests upon the bracket supporting portion 31 provided with a centrally. disposed opening 84 for the upper end of the cylindrical pintle body portion 51. 1

When the door B is in its normal position, either open or closed, the roller 63 rests in the low dwell or stop point 39 of the cam member 35. Movement of the door from this normal position causes the roller to ride upeither the camsurface 36 or the cam surface 37, depending upon which direction the door is swung. The door is, of course, raised during such movement but, as indicated in the drawing, ample space is provided between the two hinge parts of the upper hinge connectionfor this vertical movement of the door. When the door is released, it'automatically returns to its normalposition, the roller 63 travelling down the cam surface 36 or the cam surface 37 to the low dwell or stop point 39.

If it is desired to change the position in which the door normally comes to rest, all that need be done is to loosen the nut 46 and turn the enclosing member 80, and hence the cam member 35 rigidly connected thereto and therefore moving therewith, the necessary amount to bring the low cam dwell 39 to the desired position, as will be readily understood. The door need not be removed or the parts of the lower hinge connection disassembled.

For convenience of manufacture and assembly, the door openings 8 and 55 correspond in size, shape and location, as do the pintle portions 6 and 52. This enables either end of the door to be positioned at the top. as will be readily understood.

What we claim is:

1. A door hinge structure, comprising tw cooperating hinge parts, one a stationary part adapted for securement to a door post and the other a movable part adapted for securement to a door, said stationary part having a vertically disposed, generally cylindrical socket, said movable part having a one-piece pintle member having anon-circular end portion for seating engagement in a correspondingly shaped opening in the door, a generally cylindrical end portion for rotatable seating engagement in said socket, and an intermediate collar, said pintle memher being secured to said door with said non- 1 by an anchoring plate member secured to said door and having a body portion overlying said pintle collar, said plate body portion being provided with an opening through which extends said generally cylindrical pintle portion.

2. A door hinge structure, comprising two cooperating hinge parts, one a stationary part adapted for securement to a door post and the other a movable part adapted for securement to a door, said stationary part having a vertically disposed, generally cylindrical socket, said movable part having a pintle member having a non-circular end portion for seating engagement in a correspondingly shaped opening in the door, a

generally cylindrical end portion for rotatable seating engagement in said socket, and

an intermediate collar, said pintle member being secured to said door with said noncircular pintle portion in said door opening by an anchoring plate member secured to said door and having a body portion provided with an opening through which extends said generally cylindrical pintle portion, said plate body portion having one of its sides in engagement with said door and being provided in said side with a recess to receive said pintle collar.

In testimony whereof we hereby aflix our signatures.
